Sir,
Q.1: - Where the recipient is eligible for full input tax credit, the value indicated in the invoice will be treated as open market value of goods or services vide proviso to rule 28 of CGST Rules, 2017. This applies only in the case of distinct person as specified in Section 25 (4) and 25 (5) of CGST Act, 2017, that is,where the same person with single PAN has taken separate registration in different States or even in the same State and Related person.
Q2: - do not require any reply.
Q3: - Stock transfers from Head office to branches to be valued at open market value.
Q.4: - The landed cost of the imported raw material will be accepted as open market value provided whatever duties of Customs paid is included in the open market value, that is, landed cost+ Customs duties payable.
Q.5: - According to rule 28 of CGST Rules, 2017, "the value of the supply of goods or services or both between distinct persons as specified in sub-section (4) and (5) of section 25 or where the supplier and recipient are related, other than where the supply is made through an agent, shall-
(a) be the open market value of such supply;
(b) if the open market value is not available, be the value of supply of goods or services of like kind and quality;
(c) if the value is not determinable under clause (a) or (b), be the value as determined by the application of rule 30 or rule 31, in that order:
Provided that where the goods are intended for further supply as such by the recipient, the value shall, at the option of the supplier, be an amount equivalent to ninety percent of the price charged for the supply of goods of like kind and quality by the recipient to his customer not being a related person:
Provided further that where the recipient is eligible for full input tax credit, the value declared in the invoice shall be deemed to be the open market value of the goods or services.
Therefore you need not add 10% profit to the landed cost.
